JSON

JavaScript Object Notation File

JSON is a lightweight, text-based data interchange format that is easy for humans to read and write and for machines to parse and generate. It is widely used in web applications, APIs, and configuration files, supported by programming languages like JavaScript, Python, and Java, and tools like Postman and JSONLint. JSON organizes data in key-value pairs and arrays, supports nested structures, and can include strings, numbers, booleans, null values, and objects, making it versatile for representing complex data hierarchies.
